Abstract: In a remote shifter for a vehicle transmission, a transmitter unit is located near the vehicle operator while a receiver unit is mounted on the transmission. The transmitter and receiver are coupled by flexible push-pull cables that transfer the motion of the gear shift lever operated by the vehicle operator of the transmission to select and engage the desired gears in the transmission. The shift lever is operable in two independent modes of pivotal motion about orthogonal axes. Motion in the first mode controls gear fail selection in the transmission and motion in the second mode controls gear engagement. The transmitter couples the gear shift lever to the cables so that pivotal motion of the gear shift lever in a transverse plane is translated to linear motion of the select control cable while pivotal motion of the gear shift lever in the fore/aft plane is translated to linear motion of a second shift control cable. The transmitter maintains the motion of the two cables independent of one another.

The transmitter and receiver are coupled by flexible push-pull cables that transfer the motion of a gearshift lever operated by the vehicle operator to the transmission to select and engage the desired gears in the transmission. The shift lever is operable in two independent modes of pivotal motion about orthogonal axes. Motion in a first mode controls gear rail selection in the transmission and motion in a second mode controls gear engagement. The transmitter couples the gearshift lever to the cables so that pivotal motion of the gearshift lever in a transverse plane is translated to linear motion of the select control cable while pivotal motion of the gearshift lever in the fore/aft plane is translated to linear motion of the shift control cable. The transmitter maintains the motion of the two cables independent of one another.

Abstract: A dual push-pull cable controlled remote gearshift mechanism in which a control shaft is rocked about one axis to swing one cable actuator member and is rocked about a second axis transverse to the first to swing a second cable actuator member, with the coupling between the first cable and the first actuator member being substantially aligned with the transverse axis and offset from the longitudinal axis, and with the operating connection between the second actuator member and the second cable being substantially aligned with the longitudinal axis of the control shaft and offset from the transverse axis thereof. In the receiver unit, first and second coaxially interengaged shifter members are coupled to the respective cables through lever-type actuated members, one through a form of coupling that shifts one such shifter member axially in relation to the other, and the other coupling being such as to rotate the shifter members conjointly through the first shifter member in any of its axially shifted positions.

Abstract: Through dual push-pull cables, two-dimensional positioning motions and accompanying forces of an actuator device, such as a motor truck gear shift lever, are transmitted to a remote actuated device, such as the gear selector and shifter mechanism in the truck transmission. Interconnected by the cables, matched motion translators in master and slave units are rotationally and translationally guided in their respective units so as to transform two-dimensionally defined actuator motion applied to the master unit into motion components for transmission by the dual connecting cables to the slave unit, where the lineal cable motions are transformed back into a duplication of the actuator motion with accompanying forces effective to selectively operate the actuated device connected to the slave unit translator member.

Abstract: A flexure-limiting tubular ball and socket universal joint device protectively supports and guides the inner or center cable of a coaxial push-pull cable assembly while providing a seal effective to exclude dirt and moisture in the variously deflected positions of the inner member and its load-connected extension rod fitting. The cable inner member extension rod fitting passes through a support tube and a sliding seal therein, the support tube having at one end a hollow ball-shaped element that snaps into a mating socket element on a socket tube of resilient plastic material. The socket tube with the ball element retained in the socket element is then inserted longitudinally into a receptacle formed in a tubular terminal member on the outer cable.

Abstract: Self-centering action in a push-pull coaxial cable is provided by an encapsulated spring loaded device formed to be mounted as a collar encircling the end assembly of the cable by threading its inner tubular member on the conventional cable's load actuation rod and by interconnecting its outer tubular member with the cable mounting fixture or with the latter's anchor support. Occupying only a small annular space around the cable's end assembly without projecting lengthwise beyond it, the device responds to relative displacement of the cable members in either direction from a neutral position by spring reaction force that increases with displacement.
